TANNlNG-WHEEL.

SPECIFICATION forming part of Letters Patent No. 719,'713, datedFebruary 3, 1903.

Application filed June 18, 1902. Serial No. 112,Z12. (No model.)

To all whom, it may concrn:

Be it known that we, BONA ALLEN, Jr., and WILLIAM C. ALLEN, citizens ofthe United States, residing at Buford, in the county of Gwinnette andState of Georgia, have invented certain new and useful Inprovements inTanning-Wheels; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to improvements in apparatus for tanning hides,skins, and the like, and has for its object to provide a rev olubletanning-wheel which will expose the hides to the uniform action of thetanning liquor.

In our pending application, filed February' 27, 1902, Serial No. 95,956,we have shown and described an apparatus with this end in View; but itis often desirable and sometimes expedient that the hides be supportedon a vertical revolving axis instead of a horizontal axis, as shown insaid prior application, and we have therefore modified the Constructionof the apparatus to bring about this result.

In order to more fully set forth our invention, reference is had to theaccompanying drawings, in which- Figure l is an elevation of ourimproved apparatus, partly in section. Fig. 2 is a sectional plan of thetanning-wheel on the line 2 2 of Fig. 1. Fig. 3 is a side elevation of amodified form of apparatus, the tanning-vat being shown in section; andFig. 4 is a plan view of the modified form of tanning-wheel shown in Fg.3.

Arepresents the tanning-vat, adapted to be filled with the tanningliquorup to the Waterline. (Indicated in Figs. 1 and 3.)

B is a vertical shaft mounted in the bearings b b, located centrally ofthe vat.

Inside the vat the shaft B is provided with the fixed collars l and 2,having a plurality of upWardly-extending lugs 3 4. The lugs 3 arescrew-threaded to receive the nuts 5.

Supported on the shaft B by the collars l and 2 are a plurality ofdetachable frames 6, comprised of the uprights 7 and the upper and lowercross-pieces 8 and 9. The inner ends of the cross-pieces S and 9 projectbeyond the inside upright 7 and are beveled, as at 10, Fig. 2, to securerigidity of the framesections when the wheel is revolved. Theseprojecting ends of the cross-pieces are also provided with apertures 11to receive the lugs 3 and 4 of the fixed collars 1 and 2. shaft B isalso provided with a suitable collar 12 outside the vat, and to thiscollar and the outer end of each frame 6 are suitably secured thesupporting-braces 13.

Located inside of the frames 6 are the hidesupporting bars d. These barsd are arranged in a staggered series substantially diagonal of theframe, as clearly shown in Fig. 1, and are secured in any suitablemanner to the uprights 7. Upon these bars d are hung the doubled hidesor skins to be treated, and it is obvions that any number of such hidesor skins may thus be hung at one time, limited only by the number ofhide-supporting bars. Itis also obvions that although we have shown fourframes a greater or a less number may be employed, if desired.

The advantage of having the supportingbars arranged as described is thatthe bars being located in a staggered series one above the other and yetnot in the same Vertical plane allows each hide to hang perfectlystraight out of contact With the others when` the apparatus is notrevolving, as illustrated in Figs. 1 and 3, and one of the particularadvantages of nounting the hide-supporting bars in the detachable frames6 resides in the better facilities afforded for loading and unloadingthe tanning-vat. It is readily apparent by our construction that byunfastening the brace 13 and unscrewing the nuts 5 any of the detachableframes 6 can readily be removed from the vat and the hides taken ofi Orplaced upon the hide-bars, as the case maybe. Upon power being appliedto the shaft B the hides rotate rapidly through the tanning liquor inthe direction indicated by the arrows, Figs. 2 and 3, and assume asubstantiallyhorizontal position, as in Fig. 2, each hide being parallelto, but separated from, the next adjacent one. It will thereforeobviously appear that the hides being entirely submerged the action ofthe tanning liquor Will be uniform, and the entire surface of each hideor skin will at all times be fully exposed to the action of thesolution, the objectionable fea- The V IOO ture of the hides Iappingupon each other being entirely eliminated.

Although We have only shown a limited number of hide-supporting bars forthe purpose of Simplicity of illustration, this number might readily beincreased by placing the bars closer together or increasing the depth ofthe vat.

It is obvious that instead of securing the hide-bars in the detachableframes 6 these bars could be carried direct by a central post or pillar(not shown) suitably Secured to the shaft B. In this Construction wewould of course dispense with the frames 6 aitogether; but the hide-barswould be arranged in staggered groups, as hereinbefore described.

In Figs. 3 and 4 We have shown a modified form of the tanning apparatus.In this construction the bars d are disposed in spirallyarranged groupsaround a sleeve D, fixed to the shaft B.

b c 0 represent mechanism for Operating the shaft B, and C representsbrackets orjournals for supporting the driving-puliey.

Other modifications might be made without departing from the spirit ofour invention; but

What we claim, and desire to secure by Letters Patent of the UnitedStates, is-

l. In an apparatus for tanning, the com bination with a Vat, of aVertical shaft rotatable therein, and a plurality of radially-disposedhide-supporting bars carried by said shaft and arranged in staggeredgroups longitudinally thereof.

2. In an apparatus for tanning, the combination with a vat, of avertical shaft rotatable therein, a plurality of radially-disposeddetachable frames carried by said shaft and hide-supporting bars carriedin said frames.

3. In an apparatus for tanniug, the combination with a Vat, of aVertical shaft rotatable therein, a plurality of radially-disposedframes carried by said shaft, and a plurality of hide-supporting bars insaid frames and disposed diagonally thereof.

4. In an apparatus for tanning, the combination With a vat, of avertical shaft rotatable therein, collars fast to said Shaft, ap1urality of radially-disposed frames having projecting cross-pieces,provided with apertures therein adapted to engage said lugs anddetachably support said frames, and a plurality of hide-supporting barscarried in said frames.

In testimony whereof we affiX our signatures in presence of twowitnesses.
